# fclose(3)

## NAME

         fclose, fflush - close or flush a stream

## SYNOPSIS

         #include <stdio.h>

         int fclose(FILE *stream)
         int fflush(FILE *stream)

## DESCRIPTION

         Fclose causes any buffers for the named stream to  be  emptied,  and  the
         file to be closed.  Buffers allocated by the standard input/output system
         are freed.

         Fclose is performed automatically upon calling exit(3).

         Fflush causes any buffered data for the named output stream to be written
         to that file.  The stream remains open.

## SEE ALSO

         close(2), fopen(3), setbuf(3).

## DIAGNOSTICS

         These routines return EOF if stream is  not  associated  with  an  output
         file, or if buffered data cannot be transferred to that file.
